> What's so special about a 64-way box? They're expensive and customers don't expect a single userspace thread to tie up the other 63 CPUs no matter how buggy it is. It is intuitively obvious that a buggy kernel can bring a system to its knees, but it is not intuitively obvious that a buggy userspace app can do the same thing. It is more of a supportability issue than anything, because you expect the other processors to function properly so you can get in and live-debug the application when it hits a bug that makes it CPU-bound. This is especially important if the box is, say, in a remote jungle of China or something where you don't have access to the console.
The horse is dead, so lets not beat it anymore for the time being. It is quite clear that people don't want Linux to (by default) not have the gun cocked and pointed at the application developer's feet. People who want a kernel that doesn't hang in the face of bad-acting userspace apps can change the priority of important kernel threads, which seems like a reasonable workaround for now.
